Grade 9 Water Testing and Research

Grade 9 biology classes have been busy with chemical and biological stream monitoring activities in Pimmit Run this week. This lesson is just one part of Potomac’s stream monitoring protocol that supports research published by the Virginia Save Our Streams program. The research began in the fall with students measuring chemical indicators of water quality, such as pH, dissolved oxygen, nitrate, and phosphate levels. In the winter, they measured salt levels before and after winter storms. Now, students are focusing on catching and counting the macroinvertebrates. For their final project, students will analyze and explain the data they've collected to propose an "action plan" for the Potomac community based on the results. Throughout, they will add their data to the Clean Water Hub - a collection of citizen science data on stream health. Our student objectives are to evaluate the many qualities of the section of Pimmit Run that passes through Potomac’s campus and better understand ecosystem principles in a real-life situation; to become a citizen scientist and contribute to a larger set of data; and to inform our community and consider being a change agent. Experience the lesson here.

Entrepreneur and Innovation Class Students Present to Sharks

The Entrepreneur and Innovation class concluded its semester-long product-innovation program with 30-minute presentations made by 12 student groups to a panel of "Sharks." Each group comprised four students and was charged with the entire product development process, from idea generation and the development of a working prototype to the creation of sensible marketing strategies and a financial plan. Products developed included:

  • A pen that includes a fidget device and aroma therapy, designed for those who could use some calming during a test or big meeting.
  • A water bottle that has a detachable power charging station on the bottom.
  • A silent alarm in your pillow that wakes you gently via haptics programmed through an app.
  • A bottle that has four compartments, each for a different flavor of sauces that they developed.
  • A pill container that magnetically attaches to a cell phone so that pills are readily available. 

Each Shark panel included alumni with careers in business and/or engaged in product development, as well as at least one Potomac School administrator. The Entrepreneur and Innovation course is taught by three Potomac faculty members: Sean Moran, Ryan Levesque, and Harry Strong.  

Two Seniors Named Regeneron Top 300 Scholars

Congratulations to seniors Tara Bansal and Aliyah Majeed-Hall, who were named Top 300 Scholars in the Regeneron Science Talent Search 2026! Both are students in Potomac's Science and Engineering Research Center (SERC) program. This contest is the nation's oldest and most prestigious science/math competition for high school seniors. Under the mentorship of our science faculty and others, they've spent the past two years researching their projects.

- Aliyah is recognized for her research on "TRACE-Stem: A 222Rn-Calibrated Mechanistic Model of Methane (CH4) and Carbon Dioxide (CO2) Transport in Tree Stems.”

- Tara is recognized for her research on "A Novel Pneumatic Silicone Sleeve for Transhumeral Prostheses That Autonomously Regulates and Adjusts to Socket–Limb Pressure To Improve Amputee Comfort.” Read more.  

Students and Faculty Gather for Information Session on Venezuela

On Thursday, Potomac faculty from the history and world language departments, along with current senior Elizabeth Ahn, shared expertise with students and faculty to help us better understand recent events in Venezuela. Topics included international and domestic law, just war theory, background on the Maduro regime (where Elizabeth shared information from her Global Perspectives and Citizenship project), a timeline of recent events, and the historical context of U.S. intervention in Latin America. The conversation continued after the bell and in the hallways; we are looking at a potential follow-up conversation in the coming days.  

US Robotics Teams Compete Over Winter Break

This past weekend, six Potomac School teams – 12A Absolute Zero, 12B Blizzard, 12C Caffeine, 12S Syndicate, 12X EclipX, and 12Z Zap – competed at the Sugar Rush VEX V5 Robotics Competition Signature Event, a large two-day tournament in Hershey, PA that brought together 120 of the most competitive teams from 13 states and Canada.

Three Potomac teams advanced to the elimination rounds. 12B Blizzard (Rose Barabanov ‘27, Nik Bhargava ‘26, Matthew Gardner ‘26, Kate Myslewicz ‘27, Sophia Sultan ‘27, Aden Travers ‘27) finished 22nd in the qualification matches and was eliminated in the Round of 16. 12C Caffeine (Santi Cangahuala ’27, Nikhil Kothari ’27, Julian Mankovsky ’27, Trevor Nelson ’27, Cole Peterson ’27) placed 10th after qualifications and advanced to the quarterfinals, where they were eliminated by the alliance that ultimately won the event. 12Z Zap (Tony Diller ’26, Aiden Kaminski ’26, Sam Kim ’27, Deven Tuladhar ’26, Quentin Toner ’26, Sophia Vilela ’26, Alejandra Villafuerte ’26) had Potomac’s deepest run, finishing 4th in the qualification matches and advancing to the division semifinals. 

The event provided valuable high-level competition for all six teams and highlighted strong performances from multiple Potomac squads in a field of highly competitive teams. Well done to all competitors!

Constitutional Law Class Visits the Supreme Court to Hear Hamm v. Smith

On Wednesday, the Constitutional Law class visited the Supreme Court of the United States to hear the case of Hamm v. Smith. After a mad dash to arrive at the court on time, we quickly marveled at the courtroom's architecture before settling in for a two-hour argument on the question of intellectual disability and the death penalty in Alabama. Our students had read the case briefs before attending the argument and were well prepared to follow the ideas from the attorneys and the complex questions from the justices. We came away from the argument unable to predict how the court might decide this issue and look forward to reading the verdict later this term.

Grade 11 Gathers for Marshmallow Competitions and S'mores!

Last week, Grade 11 students took a break from classes and co-curriculars to have a bit of advisory-based competitive fun - with a wintery marshmallow theme! Junior class president Cait Toop organized several fun challenges for junior advisories to engage in, from structure-building with mini-marshmallows and toothpicks to a round of H-O-R-S-E with marshmallows. It was a fun break from routine, and the time together was capped off with s'mores over outdoor firepits, with much thanks to Meriwether-Godsey and Mr. Sean Conroy. Enjoy photos from recent advisory activities.
